soar MACHINE.

Application led yAugust 6, 1920. Serial No. 401,733.

To all whom t may concer/t:

Beit known that I, JULIUS A. SoHWAN'rEs, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of iVisconsin, have invented new and useful Improvements in Soap Machines, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification. This invention relates to certain new and useful improvements in cake or bar forming machines more especially adapted for use in connection with soap.

It is one of the objects of this invention t`o provide a machine for forming lengths of soap divided into a plurality of connected together bars so that the same may be conveniently dispensed and handled.

It is another object of this invention to provide a machine for forming soap into lengths of. connected together b-ars and to provide means for making suitable designations upon the bars as the same are formed A further object of this invention is to provide a machine of the class described which may be constructed to simultaneously form several strips of connected together bars of soap and which will be of light andl simple construction.

With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts 'Substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosedy invention may bemade las come within the scope of the claims.

In the accompanying drawings, I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application .45 of the principles thereof, and in which:

Figure 1 is a side view of one of my improved machines, parts thereof being broken away and in section;

Figure 2 is a top view thereof, parts being broken away and in section;`

Figure 3 is a view part in section and part in elevation taken on the plane indicated by the line 3-3 of Figure 1;

Figure 4 is an enlarged fragmentary viefw,

. or Studs 1() for detachable engagement Wit-l1 keyway slots 11 of the con-tainer. The container has its other end tapered and provided with an' opening 12 in which is removably positioned a nozzle or plodder plate 13, the plodder -plate being inserted through the opposite end of the hopper and having a flange or shoulder v14 which-is seated within a recess 15 for retaining the same in position.

The opposite sides of the nozzle or-plodder plate 13 are curved on an arc struck from the axis of two operating forming wheels 16 and 17 between which the plodder.

plate projects. The opposite sides of the adjacent container end are also curved on an arc struck from the'cen-ter of the wheel 16 and 17 as at 18, and the nozzle 13 has a central Substantially rectangular bore vor opening 19 of the size and shape it is desired to form the soap. As will be apparent, the nozzle 13 is readily removable to permit the insertion of one having a bore of a different shape or size, and the soap is forced into the hopper and out through the nozzle of plodder plate 13 between the forming rolls 16 and 17 by the plodder screw 9. The soap is maintained in the proper plastic condition by a suitable heating medium supplied to the chamber 20 surroundingthe hopper or container and having an inlet 21 and an outle-t 22, see Figure l. E

Secured to opposite sides of the container 6, by fastenings 23, at right angles to the curved sides 18 are bracket members 24 having the outer ends thereof formed with substantially vertically alined bearing members 25. The bearing members 25 that are in axial alinement have shafts 26 and 27 journaled therein and provided with .ball bearing or other connections 28, the shafts 26 and 27 having the forming rolls 16 and 17 secured thereto, yrespectively. Secured to the shafts 26 and 27 are two intermeshed gear wheels29 which insure the positive rotation of Ithe shafts and the forming rolls carried thereby at the same speed.

The forming rolls each comprise a hub portion 30 having a laterally extending disc or flange 31 integral therewith between which and a removable disc plate 32 is secured an annular forming ring or die 33. The rings 33 are provided with circumferentially extending ribs 34 at each edge thereof to form intermediate recesses, and the ribs of the rolls meet to form a. recess v35 of substantially the same shape and size as lthe bore 19 of the plodder plate 13.

The space between the ribs 34 is divided by a plurality of transverse projections 36, and the projections of the wheel 16 are timed so that those of the wheel 17 meet to form the soap 37,-passing outwardly through the opening 35 into a plurality of bars 3S by the notches 39 formed therein by said projeetions. One projection 40 of each wheel is projected outwardly level with-the ribs 34 to provide means for. cutting the strip. of soap passing therethrough once every rotation of the forming wheel so that the soap will be formed into strips of a predetermined number of connected together bars as will be readily apparent. The finished strips of bars of soap are fed onto a supporting table 41 where they are removed by an operator.

The operation of my machine is briefly as follows:

The plastic soap is forced into the container 6 by the plodder screw 9 and out through the bore 19 of the plodder plate vor nozzle 13, into the recess 35 between the rolls 16 and 17. vAs the soap in passing through the bore 19V is under pressure by the screw blade 9, this force is sufiicient to revolve the wheels 16 and 17, the soap being compressed therebetween and the projections 36 partially perforating the strips thus formed to divide the same into the bars, and the cutters 40 severing the strip from the material 'beingcontinuously fed from the hopper 6. The rings 33 of the wheels may be provided with suitable designations 42 to imprint upon the soap any name desired.

The rings 33 are readily removably secured between the discs 31 and 32 by a plurality of securing bolts 43 which permit the ready removal of the ring so that another ring of different size or design may be attached to the wheel to produce a different size or design of soa bar or cake as will be readily apparent. IP rom the foregoing description taken in connection with the accompanying drawings, it will be readily apparent that I provide a machine which will be ellicient and practical for the purpose described.

What I claim as my invention is:

1. Asoap form-ing machine comprising a soap supplying means, a pair of forming rolls provided with co-operatin'g circumferential ribs between which the material from said supply means is forced to form the material into a strip, the peripheries of said rolls having a plurality of co-operating cross ribs adapted to mark ofi:` the strip of4 material into bars, and means carrie h said rolls and adapted to sever the strip at certain predetermined points.

2. A soap forming machine comprising a soap supplying means, a pair of co-operating forming rolls between which the material from said supply means is forced to form the material into a strip, the peripheries of said rolls having a plurality of co-operating but non-engaging cross ribsadapted to mark off the strip of material into bars and a pair of .co-engaging cross ribs adapted to sever the stripat certain predetermined points.

3. A soap forming machine comprising hopper' means, soap feeding means associated therewith, one of said means having a fixed pin and the other having a bayonet slot A adapted to receive said pin whereby said last named means may be readily detached from' or connected to said hopper means, and bar forming'rolls positioned at the discharge end of said hopper means.

4. A soap forming machine comprising a soap supplying means, a pair of rolls, rims removably attached to said rolls` respectively, between which the material from said supply means is forced to form the material in to a strip, the peripheries of said rims having a plurality of co-operating but nonengaging cross ribs adapted to mark off the strip of material into bars and a pair of coengaging cross ribs adapted to severthe strip at certain predetermined points.

In testimony whereof. I aix my signature.

JULIUS A. SCHWANTES.
